Correlating equations for free convection heat transfer from horizontal isothermal cylinders set in a vertical array
TL;DR: In this article, a specifically developed computer-code based on the SIMPLE-C algorithm is used for the solution of the mass, momentum and energy transfer governing equations for steady laminar free convection from flat vertical arrays of equally-spaced, horizontal isothermal cylinders set in free air.

Natural convection heat transfer from two horizontal cylinders
TL;DR: In this paper, the surface heat transfer from a single horizontal cylinder and a pair of vertically aligned horizon-aligned cylinders is investigated for Rayleigh numbers of 2 -10 6, 4 � 10 6, 6 -106 and 6 - 10 6 and a range of cylinder spacings of 1.5, 2 and 3 diameters.

An experimental investigation on performance of annular fins on a horizontal cylinder in free convection heat transfer
Ş. Yildiz,H. Yüncü +1 more
TL;DR: In this article, a set of 18 sets of annular fin arrays mounted on a horizontal cylinder of 24.9mm diameter in atmospheric conditions was experimentally investigated and it was shown that the convection heat transfer rate from the fin arrays depends on fin diameter, fin spacing and base-to-ambient temperature difference.
